All these men worked for Ryan in 1927.
Fred Rohr was the sheet-metal foreman.
Fred Ayars (note spelling) later followed O.R. McNeel (again spelling) when they formed Ryan Mechanics to build their own designs.
Can't find Lon Wheeler, but he was most likely another of the hard working mechanics who worked for almost nothing.

A photo of the Ryan NYP "Spirit of St. Louis" at Curtiss Field (adjacent to Roosevelt Field) on Long Island, after the replacement of the original nose cone. Standing from left to right are, B.F. Mahoney, Harry F. Guggenheim, Lindbergh, and Charles Lawrance. Mahoney was the owner of Ryan Airlines, the builders of the "Spirit of St. Louis." Guggenheim, a wealthy buinessman and philanthropist from the North Shore of Long Island, had just met Lindbergh. After Lindbergh's triumphant return to the US, he and Guggenheim would assist the work of another aviation pioneer, Robert F. Goddard. Lawrance was an aeronautical engineer who was instrumental in the development of the air-cooled radial engine. His own company, the Lawrance Aero Engine Company, was purchased by Wright Aeronautical in 1923. In 1925, Lawrance would become the president of Wright Aeronautical and lead the development of the Wright J-5 Whirlwind that powered the "Spirit of St. Louis."

BF Mahoney had already purchased Ryan Aircraft. BF kept the name of the company as Ryan Aircraft leading to some confusion. see link: www.charleslindbergh.com/plane/mahoney.asp

This is a photo of Charles A. Lindbergh in front of a Ryan M-1 aircraft, not the Ryan NYP "Spirit of St. Louis."
